摘　　要：目的 探讨角膜塑形镜矫正青少年近视性屈光参差对双眼视觉的影响及临床价值.方法 回顾性临床分析研究.对2009年10月至2013年4月在南京军区福州总医院接受角膜塑形镜治疗,资料完整的23例（36只眼）屈光参差患者,持续戴镜12～50个月进行随访,观察治疗前及配戴角膜塑形镜裸眼视力（UCVA）、最佳矫正视力（BSCVA）,屈光度数变化及双眼视觉.结果 配戴角膜塑形镜1年时裸眼视力（UCVA）达到或超过治疗前最佳矫正视力（BSCVA）的百分比为：86％ （31/36）.治疗前双眼屈光参差度数为（3.08±1.42）D,配戴角膜塑形镜为（0.36±0.40）D,较治疗前明显降低.配戴角膜塑形镜近视加深度数1年时高度数眼平均增长（0.22±0.38）D,低度数眼平均增长（0.16±0.30）D.治疗前2例有正常近立体视,5例为亚正常立体视,16例为立体盲.配戴角膜塑形镜1年时,16例患者有正常近立体视,7例为亚正常立体视.配戴角膜塑形镜1年的近立体视结果与治疗前比较差异有统计学意义（x2=27.22,P＜0.01）.配戴角膜塑形镜1年的立体视结果与治疗前戴框架镜比较也有明显的改善.结论 角膜塑形镜治疗青少年近视性屈光参差不仅提高患者的裸眼视力,控制屈光度数的加深,并改善双眼视觉功能,恢复正常或部分立体视。Objective To analyze the binocular vision after wearing orthokeratology lens in adolescent myopic anisometropia.Methods Twenty-three patients of retrospective cases with binocular myopic anisometropia more than 2.50 diopters received orthokeratology lens.All patients were followed 12-50 months,to observe the uncorrected visual acuity （UCVA）,best-spectacles corrected visual acuity （BSCVA）,refraction,binocular vision before and after wearing orthokeratology lens.Results The uncorrected visual acuity was improved significantly,the BCVA of 31 eyes （86.0%） reached or more than BSCVA.In the degree of anisometropia,there was a significant difference between before treatment （3.08±l.42）D and post-treatment （0.36±0.40）D.The myopia degree increased （0.22±0.38）D in high degree myopic eye after one year treatment,（0.16±0.30）D in low degree myopic eye.The short distance stereopsis vision after wearing orthokeratology lens was significantly higher than that before treatment （x2=27.22,P 〈0.01）.And it was also significantly higher than that before treatment with corrected glasses （x2=15.51,P 〈0.01）.Conclusions Orthokeratology lens can improve the UCVA,control the development of myopia and resume the binocular vision for adolescent myopic anisometropia.
